Updating the Management Software
Allied Telesis may periodically release new versions of the management
software for this product on the company’s web site. For instructions on
how to obtain new software, see “Contacting Allied Telesis” on page 50.
To install new management software on the switches of a stack, you may
update the master switch and let that unit automatically update the
member switches for you. Here are the general steps:
1. Download the management software to the master switch of the stack
using TFTP. For instructions, refer to “Uploading or Downloading Files
with TFTP” on page 579.
2. After the master switch has received the new software from the TFTP
server on your network, it writes the file to flash memory and
automatically begins to download the new management software to
the member switches.
3. After all of the member switches have received and written the file to
their flash memories, the entire stack resets.
At this point, the stack is operating with the new management software.
Caution
This procedure is disruptive to network operations because it resets
the switches. Some network traffic may be lost.
